UNITED STATES PATENT OFFICE.

GEORGE \V. MELOTTE, OF ITI-IAOA, NEIV YORK.

REFRACTORY BED FOR SOLDERING.

SPECIFICATION forming part of Letters Patent No. 433,252, dated July 29, 1890.

Application filed June 14, 1889. Renewed February 12, 1890. Serial No. 340,155. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE XV. MELOTTE, a resident of Ithaca, in the county of Tompkins and State of New York, have invented certain new and useful Improvements in Refractory Beds for Soldering; and I do hereby declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same.

The invention has relation to a refractory bed and attachments suitable for use with a blow-pipe for soldering and like purposes, an disan improvement upon devices described in patents, Nos. 400,103 and 400,140, granted to me March 20, 1880; and its object is to improve the efficiency and facilitate the manufacture of such devices; and it consists in the matters hereinafter described and pointed out.

In the accompanying drawings, Figure 1 is a perspective view of my improved bed. Fig. 2 is a plan view of a modified form. Fig. 3 is a section on line x as, Fig. 2. Fig. 4c is a per spective View of a bed provided with a rim. Fig. 5 is a similar view of a rectangular bed and rim, and Fig. 0 is a view of a detail.

Reference-figure 1 indicates 'a bed, which, according to the present improvement, is composed of successive layers of asbestus, which may be madein band or ribbon form by weaving, braiding, or matting together in any known manner, or the fibers may be arranged, shaped, and pressed into the desired form and properly trimmed, if necessary, without forming a band or the like. The successive lateral layers 2 2 2, of which the bed is composed, as shown in Fig. 3, may be formed either by bending back on itself a continuous ribbon in successive portions, or the ribbon may be first cutin suitable lengths and the several pieces placed side by side to produce the bed. Upon two opposite sides of these layers side pieces 3, preferably of metal, are secured by bolts 4, which pass through the bed and are riveted at each end. They may, however, be fastened by screw-bolts or other like means.

IVood instead of metal may be used for side pieces, and, if desired, a receptacle for the asbestus may be provided that surrounds the asbestus on all sides, as shown in Fig. 2.

One edge of one or both side pieces is provided with holes, sockets, or slots 5, to receive the foot or shank of a clamp 6, the free end of which is adapted to be lowered upon any article it is desired to hold on the bed, and these clamps are preferably provided with a coil or other spring 7. Socketsfor the reception of the clamps may. be formed of loops or staples, as shown at 5. It is also contemplated to provide for entering the foot of a clamp in a horizontal direction, as at 5 In some cases sockets may be dispensed with and the clamp coiled about a fixed rod or other port, as shown at 5 In this case the end or foot of the clamp is continued down, so as to bear on the side of the stand or frame, as shown at 8. A clamp so secured can be moved laterally 011 its support, the coil serving both as a spring and as a means of attachment to the rod or other port affixed to the stand.

In Fig. 1 the side plates each are shown provided with a rib 0, in which are formed notches or openings 10.to receive and hold the foot of a clamp. These notches, if made in dovetail form, as shown at 11, admit the clamp by insertion from above, and hold it very securely. At 12 are shown slots provided in the flange of the side pieces for the reception of the clamps, which slots permit the sidewise adjustment of the same.

In Figs. l and 5, 13 indicates a removable rim or fire-guard adapted to retain heat on and over the bed. It absorbs heat which would otherwise be radiated into the surrounding atmosphere, and it also interrupts or diverts air-currents which might otherwise have too great a cooling effect. This rim may be made either curved or rectangular in outline. It is provided with a break or notch 14, which may vary in size, or in some cases be entirely omitted and the rim made a continuous circle, or complete hollow square or other figure. 15 shows a clamp adapted to pass over the rim or guard. The free ends of the clamp are variously fashioned, as indicated.

The general uses and capacities of the bed and some of the details of construction are described in the aforesaid patents, and further description thereof herein is unnecessary.

IIavin g thus described my invention, WhatI desire to secure byLetters Patent is as follows:

1. A bed for-soldering, made of pieces of asbestus band placed side by side and secured between side plates, substantially as specified.

2. A refractory bed forsoldering, made of straight pieces of asbestus band or ribbon placed side by side and between plates, said plates being secured together and upon the asbestus by bolts, substantially as specified.

3. A refractory bed for soldering, provided with side plates having a perforated flange, and a notched rib to receive and holdaclamp, substantially as specified.

4. A refractory bed for soldering, provided With side plates having a perforated flange, and a rib provided with a dovetail notch to receive and hold a clamp, substantially as specified.

5. A refractory bed for soldering, in combination with a clamping device having a spring coil between its clamping end and its foot, said coil embracing a guide fixed th the frame of the bed, substantially as specified.

6. Therefractory bed provided with a removable refractory open-topped rim and with an adjustable clamping device to hold the rim in place and in contact with the bed, substantially as specified.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

GEORGE V. HELOTTE.
